Bitcoin fee recommendations (sat/vB)

Updated every 10–30 seconds. Recent history is aggregated in 1-minute buckets.

Coming soon / Data not available yet

This chart will appear once the Bitcoin Fees app is online and publishing data.

How it works

• We ingest fee estimates from multiple sources (e.g. mempool explorers and public endpoints).
• The latest point is refreshed every 10–30 seconds.
• Historical points are stored for short windows (typically 6–24 hours), aggregated per minute.

API endpoints

• /api/fees/latest — current aggregated point
• /api/fees/history — historical points (supports windowMs, before/after, res=1m, limit)
• /api/fees/ingest — internal ingestion endpoint (used by the collector)
